Intel's high-NA lead and derisked stitching give its foundry technical reasons for much better returns. Per Intel, high-NA is used on selected layers of a subset of Core Ultra Series 3 processors; 18A D0 is already within high-volume manufacturing range. Stitching has been substantially derisked on XT260 and could be ready for volume production in 2027 at the earliest. The foundry turnaround remains a minority bet, and packaging was an added benefit to the high-NA case. x.com
